Re-enroll your fingerprint in Windows Hello (Settings > Accounts > Sign-in options > Fingerprint > Set up).

Body:

1. What is the Synaptics TMP 2970?
It’s not a touchpad driver. The TMP 2970 is a Trusted Platform Module (TPM) 2.0 chip from Synaptics (formerly Broadcom). It handles hardware-based cryptography – BitLocker, Windows Hello, Secure Boot, and credential storage. The Synaptics TMP 2970 Driver: A Comprehensive Overview

2. Why does it need a driver?
While TPM 2.0 is built into modern CPUs (firmware TPM), a discrete chip like the TMP 2970 requires a specific driver for Windows to communicate via SPI/I2C buses. Without it, you’ll see a yellow bang in Device Manager under “Security Devices.”

3. Common driver issues:

Code 10 (device cannot start) – Often after a Windows update or BIOS reset.
Code 28 (driver not installed) – Generic Microsoft TPM driver takes over, but features like BitLocker may fail.
Linux detection problems – Needs tpm_tis_spi or custom kernel parameters.

4. How to fix (Windows):

Official source: Lenovo, Dell, HP (who use this chip on business laptops like ThinkPad T14, Dell Latitude 5420) provide the driver as “Synaptics TPM 2.0 Device Driver” or “Synaptics TMP Firmware.”
Manual update: Go to Device Manager → Security Devices → right-click “Synaptics TMP 2970” → Update driver → Browse my computer → Let me pick → Choose “Synaptics TPM 2.0” (not Microsoft).
Recovery: If missing, extract driver from OEM’s “Chipset/TPM” cab.
Power cycle: Shut down, unplug AC, hold power 15 sec → reboot. Resets TPM state.

5. Linux users:
Most distros auto-detect with tpm_tis_spi. If not:

sudo modprobe tpm_tis_spi  
dmesg | grep -i tpm

Blacklisting tpm_crb may help if the firmware TPM conflicts.

6. Security note:
Never disable or clear the TPM without backing up BitLocker keys – you’ll lock yourself out of encrypted drives.

7. Final tip:
The TMP 2970 driver is rarely updated. If it’s broken, check for a BIOS update – OEMs often patch TPM communication bugs there. Data Transmission : The driver facilitates the transmission

Part 5: Troubleshooting Common Synaptics TMP 2970 Driver Failures

Even after installation, things can go wrong. Here are the top 5 errors and their surgical fixes.

Through IIO:

cat /sys/bus/iio/devices/iio:device0/in_temp_raw
cat /sys/bus/iio/devices/iio:device0/in_temp_scale
# Multiply raw * scale to get degrees Celsius

Part 8: Advanced – Updating the Synaptics TMP 2970 Firmware

A driver is software; the firmware is the chip's operating system. Synaptics periodically releases firmware updates to patch vulnerabilities (e.g., TPM clock glitching attacks).

Test 2: Performance Check

Run the TPM diagnostics:

tpmtool getdeviceinformation

You should see: "TPM Manufacturer ID: SYN" (Synaptics).

Error 1: "This device cannot start. (Code 10)"

Cause: The driver thinks the hardware is not responding. Fix:

Shut down your PC completely (not restart). Pull the power plug. Wait 30 seconds.
Boot into BIOS/UEFI (F2/Del at startup). Look for "Security Chip" or "TPM." Disable it, save, reboot, then re-enable it.
Reinstall the driver from step 4.

Option 1: Synaptics TMM 2970 (Touchpad Driver)

It is very common to confuse "TMP" with "TMM." If you are looking for a Touchpad driver (usually for Lenovo or HP laptops), you need the Synaptics TMM 2970 driver.

Device Name: Synaptics TouchPad
Common Hardware ID: TMM2970 or SYN
How to get it:
1. Windows Update: Go to Settings > Update & Security > Windows Update and click Check for updates. Windows usually finds this automatically.
2. Manufacturer Website: Go to your laptop manufacturer's support site (e.g., Lenovo Support, HP Support) and enter your laptop's specific Model Number or Serial Number. Look under "Mouse and Input Devices."
